Abstract
A measuring device of transparent material has a first set of numbers of uniformly increasing values from right to left with a beginning at the right and an end at the left. The numbers are aligned with lines marked at an edge of the material with inch and increment of inch spacing. The right end of the first set of numbers are located at least one-quarter of an inch from the right edge of the material. A second set of numbers of uniformly increasing values from left to right has a beginning at the left and an end at the right are aligned with the lines marked at the top edge of the material with inch and increment of inch spacing. The left end of the second set of numbers are located at least one-quarter of an inch from the left edge of the material.
Description
- This patent application claims the benefit of U.S. Provisional Application No. 61114138 filed on 13 Nov. 2008, the disclosure of which is incorporated herein by reference in its entirety.
- 1. Field of the Invention
- This invention relates to measuring devices for use by hobbyists and crafts people, and more particularly to a measuring device that has distinctive markings for both left and right handed persons.
- 2. Description of Related Art
- Transparent measuring devices are useful for measuring, marking and cutting pattern such as quilt patterns and measuring a distance between two points by both right and left handed users.
- Straight rulers, such as prior
art yard stick 11 shown inFIG. 1 is an example of a measuring device used by quilters and craft persons where the measuring device has numbers imprinted thereon which correspond to inches and divisions of inches. - Measuring devices that include two sets of numbers which are marked in upside-down orientation relative to each other located along opposed lengthwise edges of the device where each set of numbers start at the same end of the measuring device are available for right and left handed users. A prior art measuring device having two sets of numbers as described above is shown in
FIG. 2 . - With the prior art ruler shown in
FIG. 2 , a right handed user will measure a distance between a first point or line and a second point or line by placing theend 2 of the measuring device at the first point or line and reading the number on the ruler at the second point or line to measure the distance between the two points. But, for a left handed user to read the measurement right-side-up, the ruler must first be turned upside down andfirst end 2 of the measuring device is placed to the left of the point or line from which the user is measuring. - If the
end 2 of the measuring device is positioned for the user to measure from right to left, said user will need to twist the ruler upside down and therein read the numbers on the ruler upside down as well. - It is an object of the present invention to provide an improved ruler in which the above disadvantages are substantially obviated.
- It is another object of the present invention to provide a measuring device which can be used to measure a distance between two points or lines without having to read an aligned set of uniformly increasing numbers that are upside-down.
- It is a further object of the present invention to provide a measuring device that has two sets of uniformly increasing measurement numbers where each set of numbers are readable right-side-up whether a measurement is from right to left, e.g., when the first point from which a user is measuring is located to the right of that point, or whether a user is measuring from left to right, e.g., when the point from which a user is measuring is located to the left of the point.
- The measuring device here disclosed can be used to measure a distance from a first point to a second point where one end of the ruler is a reference end for one of two separate scales and the opposing end of the ruler is a reference end for the other scale.
- The ruler is made of flat transparent material where one end is a reference end for a first set of numbers in ascending order; and the opposite end is a reference end for a second set of numbers in ascending order. Thus, the flat transparent material has two sets of numbers which are in inches and increments of inches where one set of numbers increase in value when read from left to right, and the second set of numbers, that are also printed along the same edge of the transparent material increases in value when read from right to left. Each of the two sets of numbers are in an upright position whether measuring from right to left or from left to right and one set of numbers is located below the other.
- The foregoing has outlined, rather broadly, the preferred feature of the present invention so that those skilled in the art may better understand the detailed description of the invention that follows. Additional features of the invention will be described hereinafter that form the subject of the claims of the invention. Those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiment as a basis for designing or modifying other structures for carrying out the same purposes of the present invention and that such other structures do not depart from the spirit and scope of the invention in its broadest form.
- Other aspects, features, and advantages of the present invention will become more fully apparent from the following detailed description, the appended claim, and the accompanying drawings.
